Safety and Efficacy Comparison of Docetaxel and Ixabepilone in Non Metastatic Poor Prognosis Breast Cancer

Registration Number
NCT00630032
Lead Sponsor
UNICANCER
Brief Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving them after surgery may kill any tumor cells remaining after surgery. It is not yet known whether docetaxel is more effective than ixabepilone when given after surgery and combination chemotherapy in treating breast cancer.

PURPOSE: This randomized phase III trial is studying giving combination chemotherapy followed by docetaxel or ixabepilone to compare how well they work in treating patients who have undergone surgery for nonmetastatic breast cancer.

Detailed Description

OBJECTIVES:

Primary

* To evaluate the benefit from sequential administration of 3 courses of combination chemotherapy (FEC100) followed by 3 courses of ixabepilone versus docetaxel on the 5-year disease-free survival of women with nonmetastatic, poor-prognosis breast cancer.

Secondary

* To compare the 5-year distant metastasis-free survival.

* To compare the 5-year event-free survival.

* To compare the 5-year overall survival.

* To compare the safety profiles for the two chemotherapy regimens.

* To identify and/or validate predictive-gene expression profiles of clinical response/resistance to the two treatment regimens.

* To bank frozen and fixed tumor and frozen serum prospectively for future translational studies in both genomics and proteomics (transcriptome and proteome analyses, tissue array analyses).

* To compare the cost-effectiveness of these 2 regimens.

* To compare the quality-of-life of patients treated with these 2 regimens.

OUTLINE: This is a multicenter study. Patients are stratified according to participating center, menopausal status (pre- vs post-menopausal), and tumor hormone-receptor status (triple-negative vs progesterone-receptor negative, HER negative, and estrogen-receptor \[ER\] positive). Patients are randomized to 1 of 2 treatment arms.

* Docetaxel Arm: Patients receive epirubicin hydrochloride IV, fluorouracil IV, and cyclophosphamide IV every 3 weeks in courses 1-3 and docetaxel IV alone every 3 weeks in courses 4-6.

* Ixabepilone Arm: Patients receive treatment in courses 1-3 as in arm I and ixabepilone IV alone every 3 weeks in courses 4-6.

In both arms, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients also complete a quality of life questionnaire periodically.

After completion of study treatment, patients are followed periodically for up to 10 years.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Disease-free Survival (DFS)At 5 years

DFS is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or death from any cause, whichever occurs first

Secondary Outcome Measures
NameTimeMethod
Number of Disease-free Survival Events for Triple-negative SubgroupAt 5 years

DFS is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or death from any cause, whichever occurs first in participants with triple negative breast cancer only.

Number of Disease-free Survival Events for ER+/PR-/HER2- SubgroupAt 5 years

DFS is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or death from any cause, whichever occurs first in participants with ER+/PR-/HER2- breast cancer only.

Number of Distant Metastasis-free Survival Events for the Whole PopulationAt 5 years

The distant metastases-free survival is the length of time during and after the treatment for cancer that a patient is still alive and the cancer has not spread to other parts of the body.

Overall SurvivalAt 5 years

The overall survival is the length of time from randomization that patients enrolled in the study are still alive.

Number of Event-free SurvivalAt 5 years

The Event-free Survival is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or the date of second neoplasia, or the date of death from any cause, whichever occurs first.
